Foreclosures in Beaufort County

I have a few friends who go to the foreclosure courts in Beaufort County. I was told by them that, the homes around here that are going into foreclosure are being bought back by the banks. What is that all about? DO the banks know something that we don't or is it that the banks have to spend all that TARP money and this is how they are doing it. There were about 30-40 foreclosures in Pine Crest that were bought back also. And people are starting to say they are selling their houses again. Anyone want to bite on this one.
